From the review:
"Your goal is simple. There's a line near the bottom of the screen and a number of cuddly gerbils piled up above the line, you have to get them below the line within a set number of turns. Your only methods to do this are through the use of bombs, ropes and disintegration. Considering the amount of explosives used in this game, it's good to see that the gerbils are somehow never hurt throughout each level, despite frequently being propelled across the screen by various explosions."
